W niniejszej pracy podjęto próbę poprawy właściwości cementowych kompozytów konstrukcyjnych [CKK] stosując dodatek dwóch rodzajów włókien. Zbadano pięć różnych dodatków włókien, w tym trzy składy z pojedynczym rodzajem włókien o udziale objętościowym 2,0%, natomiast pozostałe dwie mieszanki hybrydowe zostały opracowane z dwoma rodzajami włókiem. Składy hybrydowych CKK ustalono stosując mieszaninę włókien o małym module - włókna z poli(alkoholu winylowego) i włókien o dużym module - stalowych i szklanych. Trzy warianty składu wykonano z włókien metalowych, szklanych i włókien z poli(alkoholu winylowego). Hybrydowe mieszanki włókien przygotowano mieszając 2/3 włókien z poli(alkoholu winylowego) i 1/3 włókna metalicznego w udziale łącznym wynoszącym 2,0% objętościowych oraz 2/3, włókien z poli(alkoholu winylowego) oraz 1/3 włókien szklanych. Ta metoda dała dobry wynik z punktu widzenia właściwości CKK, przy rozciąganiu i zginaniu. Na podstawie tych wyników stwierdzono, że włókno z poli(alkoholu winylowego) w udziale 2/3 i włókno szklane o udziale 1/3, z sumarycznym udziałem objętościowym 2,0%, wykazują korzystne właściwości.

In this study, an effort was taken to progress the performance of Engineered Cementitious Composites [ECC] mix, by incorporating two different fibers. Five different proportions were subjected to investigation, in this three different proportions were developed with single fiber with 2.0% volume fraction, other two proportions were with two types of fibers. Hybrid ECC proportions were organized through the mixture of low-modulus fibers [poly(vinyl alcohol) fiber] and high-modulus fibers [steel and glass fibers]. Three proportions were made with metallic, glass fiber and poly vinyl alcohol fiber. The hybridation proportions were made with a 2/3 fraction of poly vinyl alcohol fiber and 1/3 fraction of the metal fiber in 2.0% of volume fraction and accompanied with poly vinyl alcohol fiber 2/3 fraction and 1/3 fraction of glass fiber. This procedure has a good rate of success in tensile and bending behavior of ECC mix. From this effort, it was concluded that poly(vinyl alcohol) fiber 2/3 fraction and 1/3 fraction of glass fiber in 2.0% volume fraction, displayed reasonable traits.
